Instead of having a battery’s anode and cathode on either side of a nonconducting separator, a new battery would intertwine the two in a self-assembling, 3D gyroidal structure. Thousands of nanoscale pores will be filled with the components necessary for energy storage and delivery.

This three-dimensional architecture basically eliminates all losses from dead volume in the battery. Shrinking the dimensions of these interpenetrated domains down to the nanoscale, gives orders of magnitude higher power density. In other words, you can access the energy in much shorter times than what’s usually done with conventional battery architectures.
